BAR HARBOR - Improvisational comedy is one of the ultimate high-wire acts in the entertainment realm. Watching as a group of quick-thinking, quicker-witted actors strive to generate engaging performances on the fly can be both exhilarating and exhausting when improv is good, it can be very good, but when it’s bad? It’s BAD.

However, when it comes to the work being done by ImprovAcadia, a short-form improv theater just beginning its 15th season at 15 Cottage Street in Bar Harbor, you’ll never have to worry about the latter. This is a group that is inevitably powered by speed and smarts, bringing some of the best improv you’re likely to see anywhere right into our own backyard.
